Raindrop is based on a machine made by the University of Manchester in the early 1970s to study rain. The original design has been modified during a two-year long process of experimentation in order to sustain a single drop of water hovering in mid air above the specially designed wind tunnel.

"Raindrop comprises a machine built to allow a drop of water to hover in mid air. Viewing this translucent, jewel-like object instils a very bodily sense of unease. Arrested in free-fall, its form mechanically maintained in a seeming repudiation of basic physics, the stationary raindrop throws us off balance, making us feel as though we were plummeting to the ground in its place."
